Spudgers!

A spudger (apparently) is a plastic device for prising open the cases of electronic items to get into them to repair them. You can use a flat-bladed screwdriver, but will probably crack or score the case unless you are both lucky and careful. 

I never throw out used toothbrushes because they are invaluable for cleaning and degreasing engine parts (EGR valve on a Skoda Fabia being a personal favourite!). It occurred to me that they would make good spudgers with a bit of, well whittling I'd guess you'd call it. If I'm honest, the inspiration was the classic jailhouse shank actually. 

Get your Stanley knife and instead of using it for a thrill-seeker liquor store hold up (putting you in the aforementioned jailhouse), whittle the tops of a couple of old toothbrushes into fine spade ends. Ideal for opening radios, DVD players and especially tablet computers.

Free and greener than just chucking them away.
